PTC NTC Thermistors Comparison
Thermistor, abbreviated for THERMally sensitive resiSTOR.
PTC, abbreviated for Positive Temperature Coefficient.
NTC, abbreviated for Negative Temperature Coefficient.
PTC thermistor resistance increases with temperature rising.
NTC thermistor resistance decreases with temperature rising.
PTC Thermistor major material BaTio3, NTC thermistor major material is Mn, Ni, Cu.
PTC thermistor is mainly applied in over-current overload and short circuit protection, telecom protection, lighting soft switching time delay, motor starting, temperature sensing & protection, self-regulation heating, etc.
NTC thermistor is mainly applied in inrush current suppressing limiting, temperature sensing measurement, temperature compensation, temperature control, etc.
